3 Claims.

The invention relates to windows having foldable and slidable window sections, more particularly to the windows of closed-vehicle doors and especially to vehicle door windows the adjustable transparent sections of which are readily converted to a means of stimulating the Ventilating movement of air through the interior of the vehicle during the overland movement of same; and the invention consists substantially in the construction, combination and arrangementl of elements hereinafter pointed out and recited more particularly in the claims.

It is a primary object of the invention to provide a Vehicle window with movable sections and L, means to convert such sections to a Ventilating mechanism by motion transmitted from a single source. l

It is also a primary object to provide a vehicle window having two movable sections, one of which is rotated to Ventilating `position, and the other of which is both slid to rotatable position,

and then rotated during the rotation of the first,

section.

The above and other objects are attained by the constructionA and arrangement of parts hereinafter explained in connection with the accompanying drawings, in which: f

Figure l is a fragmentary sidev view of the mechanism, shown partly in section and serving as a movement diagram of the window operating mechanism;

Fig. 2 is a cross-sectional view taken in the proximity of line 2-2 of Fig. l;

Fig. 3 is a detail cross-sectional view taken in the proximity of line 3-f-3 of Fig. l;

Fig. 4' is a detail cross-sectional view taken in I the proximity of line 4--4 of Fig. 1;

Fig. 5 is a cross-sectional view taken in the proximity of line 5-5 of Fig. 1;

Fig. 6 is a detail sectional view taken in the proximity of line 6--6 of Fig. 1; and,

Fig. 7 is a detail sectional view taken in the proximity of line I4-I of Fig. 1.

Similar characters of reference designate similar parts throughout the several views.

Referring to Fig. l the numeral I indicates a portion of the vehicle door, the Window thereof consisting of the forward glass section 2 and the rearward glass section 3,' which` are 'provided with metallic frames 4 and 5, respectively. The forward section 2 is adapted to be turned on th'e trunnion 6 whichjournals downwardly through the window sill 1, and another corresponding trunnion 6A positioned directly over the trunnion 6, and which is secured to the upper edge of said forward section and pivoted in the upper door structure. Said section is thus first swung on said trunnions into the position indicated by the dotted lines 8 of Fig. 5. Y

The rearward section 3 is slid toward' the forward section 2, on the window sill 'I during the initial turning movement of the forward section 2, and until the forward corner of said rearward section slides onto the turn-table 9 between the guides IB. A corresponding inverted turn-table 9A is pivoted directly over the turn-table 9 in the upper door structure and the upper forward corner of said rearward section slides under same between the guides thereof. Said rearward section is then turned between said turn-tables to a position indicated -by the dot-and-dash lines II, while the'foiward section 2 is turned from the position indicated by the dotted lines 8 to the position indicated byv the dot-and-dash lines I2.

The trunnion 6 extends from the forward secit journals. T he lower end of said trunnion mounts the bevel gear I3, and the bevel gear quadrant I4 meshes therewith said gear quadrant i necting rod I9, and the other'or `free en'd of the lever 20 is provided with a stud 22 parallel to the axial line of the pivotal connection 2l.

tion 2 downwardly through the sill 1 in which Between the free end of the lever l1, and its A fulcrum I8, the U frame 23 is secured as shown in Fig.V 2, to the side of the lever l1, and the threaded nut 24 is trunnioned to said lever and frame, by its trunnion 25. One end of the substantially horizontal screw 26 operates in freevthreaded relation with said nut and the other or rearward end of said screw mounts the worm gear 2'I which meshes with the worm 28. Said worm 28 is in turn mounted Aon one end of the shaft 29, which journals through the vehicle door structure, and the inner end of which protrudes interiorly of the vehicle.V Said inner shaft end transmitted from said crank to the worm 28, the

wormwheel 21, the screw 2B, the nut 24, the lever I1, the connecting link I 6, the quadrant gear .|4,' the bevel gear I3, and trunnion 6, in order For shifting .the rearward window section 3, a puller for same is providedin the form of the vertical plate 3|. Said plate is concealed on all sides by the door structure and is suspended in substantially the same plane as said rearward section, directly below the sill 1.. The horizontal slides 32 are formed along the upper edge of said plate, paallel tothe lower edge of said rearward section, and form a T iron construc- "sidering the vehicle as a whole, and a stud f so secured to said rearward section, extends downwardly therefrom normally into engagement with said hook, by which arrangement it will be understood that shifting of the plate 3| in vthe guides 33, will correspondingly shift said rearward window section by engagement of said hook with the stud 35. i

To thus shift said rearward section by means of the plate 3| a vertical slot 39 is formed in same the sides of which straddle the stud 22, carried by the lever 29, as above described, and as the lever I1 is swung in rotating the forward window section 2, the lever 29 is swung thereby throughthe connecting rod I9, and the stud 22 and plate 3|, being correspondingly shifted forwardly, it will be obvious that the rearward section 3 is shifted to the position inidicated by the dotted lines 31 during the period the forward section 2 is rotated to a position indicated by the dotted lines 9. i

As above indicated the rearward window section 3 slides onto the turn-table 9, as it reachesv its most forward position, and said section is confined laterally between' the guides I 9 of said turn-table, and bythe corresponding guidesoi' the turn-table 9A. Having reached the end of its forwardly sliding movement said rearward section is rotated by the turn-table 9, into a position indicated by the dot-and-dash lines II,

49, which in turn meshes with the intermittent Igear-4I which is mounted on the lower extremity of the-trunnion 9. When the forward section 2 has been rotated to the position indicated by the dotted lines 3, the teeth 42 of the intermittent gear 4|, engage'the teeth 43 of the intermediate gear 49, and the rearward window section 3, having been slid ontov the turn-table 9, said rearward ,l section is swung thereby into the position indii cated by the dotanddash lines I I, while said 'forward section is rotated from the position indicated by the dotted'lines 9 to the position in- "dicated by the dot-and-dash lines I2.

To carry'out the final turning movement of saidl forward section by the screw 26 through the- -lever I1 which is coupled to the lever ZIJQby means of the connecting rod I9, and without continued .sliding movement of the plate 3|, the pivotal connection between said connecting rod, and the lever I1 is comprised of a at sided stud 44 secured to the lever 1, theconnectingl rod |9 forming a female mating pivot head 45 bearing on said stud 44. A vacancy 49, however, vis provided in said pivot head of suitable size, and suit. able location to permit said stud to pass edgeways therethrough, when said rearward section has reached the end of its forward travel, and when said stud has been correspondingly rotated by the lever I1, by which lfeature said stud continues its movement through said vacancy with said lever |1, without further movement of the connecting rod |9,. the lever 23, the plate 3|, andthe hook 34, and to further adapt the lever I1, and connecting rod I9 to this Working relation, a slotted extension 41 is formed on said connecting rod the slot 48 of which is a continuation of the vacancy 46. .Said slot is curved about the pivot I9 of the lever |1 as considered when the said connecting rod and said lever are'in the position indicated by dotted lines 49 shown in Fig.y l, by which arrangement said slot serves to feed said stud back into pivotal relation with the head 45, at the end of the reverse movement of said stud through said slot, and when the intermittent gear 4| has rotated the driven gear 49 reversely into nonrotation position.

Referring to Fig. 1 in view of Fig. 4, the turn- .table 9 is provided with a notch 59 in the forwardv side thereof, said notch being in-line with the sliding path of the rearward window section 3. A plunger 5I is slidably disposed in the structure of the sill 1 suitably to .be maintained, one end in engagement with the notch 59 during the sliding movements of said rearward section, the expansion coil spring 52 being tensioned against the other end ofsaid plunger and tending to con'- stantly force said plunger in said notch, and normally keep the turn-table guides I9 in linefwith said rearward section. The guides I 0 of the turntables 9 and 9A are flush with the upper surface ofthe sill 1 and the lower surface of the corresponding above door structure, and therefore do not protrude into the path of rotation of the forward section 2; and the parts of said rearward section which engage the guides I9 of the turn-tables 9 and 9A, respectively, extend below and above the section proper in the form of keys 53; and said keys pass between the guides I9 suiilciently close to the door of the turn-table 9 to strike the upper rearward corner of the plunger 9|, and push same out of engagement with the notch 59, leaving said turn-table free to rotate with said rearward section as above described.

As above indicated said rearward window section is slid by the hook 32 of the'plate 3| into ro-y tating position, said hook engaging the stud 35 of said section. When', however, said section is rotated as above described said-stud is swung out of engagement with said hook as indicated by the arrow 94 in Fig. 7, by which feature it will be understood that said section is automatically uncoupled and coupled with said plate to permit rotation of said section with the turn-table 9.

'I'he rearward end of the screw 29, with the worm wheel- 21, is journaled in the frame 99 which straddles the worm 29, and pivots floatingly. over the shaft v2i), by which arrangement it will be understood that said screw and worm wheel frame swingfreely upon said shaft to follow the and fallof the nut 24 in accordance wlth'the circular path v'determinable by the moveadsense ment of said nut with the lever il, about the fulcrum I8.

The rearward section 3 is guided in its`sliding movement by the guide strips 56 and 51, which' are secured to the window sill 1. The guide 56 extending a more limited distance forward, and being suiiieiently short to clear said rearward section in therotatingmovement thereof.

While the description and drawings illustrate in a. general way certain instrumentalities which may be employed in carrying the invention into effect, it is obvious that many modications may be made in the various details without departing from the scope of the appended claims, it being understood that the invent; `n is not restricted to the particular examples n 1 The invention claimed is:
